### Function

# GLibUnix Pipe close

since: 2.80

#### Declaration [src]

    gboolean
    g_unix_pipe_close (
      GUnixPipe* self,
      GUnixPipeEnd end,
      GError** error
    )

#### Description [src]

Close one of the ends of the pipe and set the relevant member of `fds` to `-1` before returning, equivalent to g_clear_fd().

Like g_close(), if closing the file descriptor fails, the error is stored in both %errno and `error`. If this function succeeds, %errno is undefined.

This function is async-signal safe if `error` is `NULL` and the relevant member of `fds` is either negative or a valid open file descriptor. This makes it safe to call from a signal handler or a `GSpawnChildSetupFunc` under those conditions. See `signal(7)` and `signal-safety(7)` for more details.

To close both file descriptors and ignore any errors, use `g_unix_pipe_clear()` instead.

Available since: 2.80

This function is not directly available to language bindings.

#### Parameters

`self`

  Type: `GUnixPipe`

  A pair of file descriptors.

  The data is owned by the caller of the function.

`end`

  Type: `GUnixPipeEnd`

  One of the ends of the pipe.

`error`

  Type: `GError **`

  The return location for a recoverable error.

  The argument can be `NULL`.
  If the return location is not `NULL`, then you must initialize it to a `NULL` `GError*`.
  The argument will be left initialized to `NULL` by the function if there are no errors.
  In case of error, the argument will be set to a newly allocated `GError`; the caller will take ownership of the data, and be responsible for freeing it.

#### Return value

Type: `gboolean`

`TRUE` on success.
